OILING DEVICE Filed July 25, 1930 2 Sheets-Sheet 2 INVENTOR WITNESS 5 f'raa/ ,ij ayfie Zia. %4/1 c BY ATTORNEY Patented May 8, 1934 ise 11 Claims.

The invention relates to oiling devices, and particularly to devices for oiling guide rails in elevator shafts.

An object of the invention is to provide an I oiling device movable relatively to a member which is operatively engaged by a part of the oiling device to feed oil when the oiling device moves relatively to the member, the rate at which the oil is fed by the oiling device being regulated by the speed of the oiling device relatively to the said member.

The invention has for another object to provide a pump for pumping oil to a guide rail in an elevator shaft, the pump being operated by a member in engagement with the elevator shaft.

Still another object of the invention is to provide an eccentric engaging a member, the rotation of the eccentric by the member serving to operate an oil pump.

Still other objects of the invention are to provide an adjustable mounting for the eccentric to regulate the action of the pump with relation to the eccentric and to provide the eccentric with a cork periphery which engages a member for rotating the eccentric.

The invention has for a further object to provide an oiling compartment to which the oil is fed by a pump, there being oiling or lubricant members in the compartment which are pressed 0 by springs against an elevator guide rail, or other member. Any excess oil in the oiling compartment is returned to a reservoir leading to the pump.

Another object of the invention is to provide means to feed oil from a device in proportion to the distance traveled by the device, the said means only feeding oil when the device is in motion.

Additional objects of the invention will appear in the following specification in which the preferred form of the invention is described.

In the drawings similar reference char ct s refer to similar parts in all the views, of

Figure 1 is a side elevation partially in se illustrating my oiling device as mounted on a shoe for engagement by a guide rail in an elevator shaft,

Figure 2 is a sectional view on the line 2-2, of Figure 1,

Figure 3 is an enlarged sectional View illustrating the pump which serves to feed the oil to the oiling compartment,

Figure 4 is a sectional View On the line 4-4 of Figure 1,

Figure 5 is a sectional view on the line 55, of Figure 6, and

Figure 6 is an enlarged side elevation of the eccentric.

By referring to the drawings it will be seen that the oiling device is shown as applied to an elevator shaft having a guide rail 10, a shoe 11 which is mounted on an elevator being positioned to travel on the said guide rail.

The oiling device has a supporting member 12, one end 13 of which is bent upwardly to form a standard, and on this supporting member 12 there is mounted a bearing member 14 to which are pivoted at 15 arms 16, these arms 16 being two in number and one being disposed at each side of the bearing member 14, as illustrated in Figure 2 of the drawings. Each arm 16 has a slot 17 therein and disposed in these slots 17 there is a shaft 18 which is held in adjusted position in the said slots 17 by nuts 19. Disposed between the arms 16 and mounted on the shaft 18 there is an eccentric 20, as best shown in Figures 5 and 6. As will be seen by referring to' Figure 5; the periphery 21 of this eccentric is manufactured of cork, the said cork periphery being disposed between the side plates 22 of the eccentric and being held in position by rivets 23 which extend through the side plates 22 and through the cork periphery 21. The hub 24 of the eccentric has upwardly disposed flanges 25 which engage the outer sides of the inner ends of the plates 22 to hold the said plates 22 in position, there being preferably a collar 26 disposed between the plates 22 and also between the hub 24 and the cork periphery 21. This eccentric 20 is mounted on the shaft 18, as has been stated and the shaft with the eccentric is held in adjusted position in the slot 17 by the nuts 19. There is also mounted on the shaft 18 a shield 2'? which serves to preoil from sputtering about the shaft as the c rk pez-phery 21 of the eccentric 20 rotates on the guide rail 10.

Secured to the shield 2'? there is a rod 28, the said rod passing through a slot 29 in the stand- 13 and having a nut 30 at its outer end beyond standard 13 to limit the inward movement 0;? the rod 28. There is also a spring 31 mounted on the rod 28 and disposed between the standard 13 and the shield 27 for holding the shield 27 extended with the arms 16 and the eccentric 20 so that the cork periphery 21 of the eccentric will at all times frictionally engage the guide ra l 10. This cork periphery 21 is provided to make certain that the eccentric will at all times a gland 35 held by the usual nut 36 in a pump member 37, the pump member 37 being secured to a pump 38 having an outlet valve seat 39 andan inlet valve seat 40, a ball valve 41 being provided for seating at the outlet 39 and a ball valve 42 being provided for seating at the inlet 40. It will, therefore, be seen that with the arms 16 and by means of the eccentric the piston 34 will be reciprocated, which will draw a fluid inwardly through the inlet and force the fluid'outwardly through the outlet 39 to the communicating 20 means 43 leading to the top of an oiling compartment 44'. Disposed below the supporting member 12 and secured thereto by straps 45 there isa reservoir 46, the pipe or communicating means 47 extending from the interior of this 25 reservoir 46 to the pump inlet 40.

The oiling compartment 44 is best shown in' Figure 4 of the drawings, and it will be seen that this oiling compartment 44 has an opening- 48 through which the guide rail 10 is disposed. 36-- Contained in the oiling compartment there is a plurality'of oiling members 49 and 50 which are preferably three in number, there being two oiling members 49, one disposed at each side of the guide rail 10," and an oiling member 50 disposed at the end of the guide rail 10. Leaf springs 51 are provided for pressing the oiling members 49 and 50against the guide rail 10. As has been stated the pipe or communicatingmeans 43 leads to the oiling compartment 44. There is also a 40* pipeor communicating means 152 leading from the'side of the oiling compartment 44 to the res efvoir'46:
